Installation Devstack安装失败，错误消息为“0”；错误：不允许将可编辑需求作为约束”；

运行脚本stack.sh时遇到以下错误：

DEPRECATION: Constraints are only allowed to take the form of a package name and a version specifier. Other forms were originally permitted as an accident of the implementation, but were undocumented. The new implementation of the resolver no longer supports these forms. A possible replacement is replacing the constraint with a requirement.. You can find discussion regarding this at https://github.com/pypa/pip/issues/8210.

再高一点我有个警告：

    Found existing installation: pip 21.1.1
    Uninstalling pip-21.1.1:

知道为什么吗？

感谢您的帮助，

err\u trap

功能可以捕获任何错误。你能在你发布的第一个片段上面添加什么吗？它可能包含导致错误的操作。这个错误消息本身并没有引起我的注意。我已经用更多的信息编辑了我的问题。您试图安装它的操作系统和版本是什么？它是Ubuntu 18.04.5 LTST，是受支持的Ubuntu版本。如果它是一个干净的安装，并且您使用了Devstack的最新更改，那么我不知道从哪里开始。
